Hypoxia’s Effects on the Shrimp Fishery in the Nor...

Our research is the first to investigate hypoxia’s effects on the harvest and economic dynamics of a Gulf of Mexico shrimp fishery. By linking hypoxia to impacts on fisheries, we ...

Impacts of Hypoxia on Fish and Fisheries in the No...

To protect fisheries and support ecosystem-based resource management in the northern Gulf of Mexico, we are developing modeling tools that will evaluate and simulate how large-scale changes in forcing factors ...

Integrated Ecosystem Modeling of the Causes of Hyp...

The largest low oxygen (hypoxic) zone affecting the United States is in the northern Gulf of Mexico, adjacent to the Mississippi River. This “dead zone” in the Gulf of Mexico ...

Mechanisms Controlling Hypoxia – Integrated Causal...

We’re examining the complex physical and biogeochemical relations that control and maintain the low-oxygen dead zone in the northern Gulf of Mexico (nGOM). We are combining field data from moored ...

Modeling Impacts of Hypoxia in the Northern Gulf o...

We are determining the effects of hypoxia (low dissolved oxygen) on reproduction of fish (Atlantic croaker) throughout the northern Gulf of Mexico to accurately model population outcomes and to assess ...

Operational Gulf of Mexico Hypoxia Monitoring

The Gulf of Mexico hypoxia monitoring cruise is an annual shelf-wide survey of the Gulf's hypoxic area (i.e., “dead zone”) and the survey is the metric used by the interagency ...

Synthesis and Integrated Modeling of Long-Term Dat...

We are integrating existing data sets collected in the Northern Gulf of Mexico to study hypoxia impacts on coastal ecosystems and associated fisheries. We are using probabilistic, data-centric modeling to ...

Transitioning to Operations NOAA Supported Statist...

The Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA) mandates the development of scientific tools for natural resource managers to address hypoxia in coastal ecosystems. In response, NCCOS ...

User-Driven Tools to Predict and Assess Effects of...

We are developing user-friendly, management-scale forecasting tools and quantitative indicators for hypoxia impacts on the Northern Gulf of Mexico ecosystem. We will assess minimum data needs to ensure these forecasts ...

Using Linked Models to Predict Impacts of Hypoxia ...

We are linking a suite of well-established models to quantify fish and shrimp population responses to combinations of nutrient loadings and planned river diversions. Our scenario analyses include different land-use ...

Decision Support Tool Visualizing Effects of Nutri...

The NCCOS Northern Gulf of Mexico Ecosystems and Hypoxia Assessment Program (NGOMEX) has produced various ecosystem models that predict the effects of hypoxia on living marine resources.  Although such models ...

Below Average Summer 2023 ‘Dead Zone’ Measured in ...

NCCOS-supported scientists have determined that this year’s Gulf of Mexico “dead zone” — an area of low oxygen that can kill fish and marine life — is approximately 3,058 square ...

New Funding to Reduce Nutrient Pollution Reviewed ...

The Gulf of Mexico Hypoxia Task Force held its 37th annual meeting in December to review ongoing actions to improve water quality in the Mississippi River basin and to discuss ...

Third Gulf of Mexico Hypoxia Task Force Report to ...

The Gulf of Mexico is home to the largest annual hypoxic zone in the United States, an area of low oxygen which puts at risk valuable commercial and recreational fisheries ...

NOAA Forecasts An Average ‘Dead Zone’ for Gulf of ...

NCCOS scientists are forecasting this summer’s Gulf of Mexico hypoxic zone or “dead zone”—an area of low to no oxygen that can kill fish and other marine life— to be ...

Researchers Determine Flood Risk for 13 Coastal Co...

Coastal communities need to know what actions to take to mitigate flooding, now and in the future as sea level rises. A new NCCOS-funded study helps meet this need by ...

Gulf of Mexico Dead Zone Task Force Convenes to Di...

The Mississippi River Gulf of Mexico Watershed Nutrient Task Force, otherwise known as the Hypoxia Task Force (HTF), held a virtual fall meeting from December 13- 14, 2021. The Task ...

Phytoplankton on Louisiana Shelf Show Seasonal Com...

NCCOS sponsored researchers analyzed common phytoplankton taxa and accompanying environmental data for 672 surface water samples collected from 95 stations located on the Louisiana/Texas shelf (Gulf of Mexico) between 1990 ...

Larger than Expected Summer ‘Dead Zone’ Measured i...

Map of measured Gulf hypoxia zone, July 25–31, 2021 (LUMCON/NOAA). Red area denotes 2 mg/L of oxygen or lower, the level which is considered hypoxic, at the bottom of the ...

Bacterial Removal of Nitrogen, Methane from Gulf D...

NCCOS-supported researchers have determined the natural removal rates of nitrogen and the potent greenhouse gas methane from Louisiana's coastal waters. The study investigated patterns of pelagic denitrification (bacterial conversion of ...

Dead Zone

Since its inception in 1990, the National Centers for Coastal Ocean Science has provided the research foundation upon which management of the "dead zone" in the Gulf of Mexico is ...

Funding Opportunities

NCCOS supports the Competitive Research Program (CRP) and the RESTORE Science Program that provide the critical information and predictive capabilities required to manage the nation’s coastal resources in an ecosystem ...

HABHRCA

Harmful algal blooms (HABs) and hypoxic events (severe oxygen depletion) are some of the most scientifically complex and economically damaging coastal issues challenging our ability to safeguard the health of ...

NGOMEX

The northern portion of the Gulf of Mexico ecosystem, a region containing almost half of the nation's coastal wetlands and supporting commercial fisheries generating $1 billion annually, has undergone profound ...

Outputs and Outcomes

Clear articulation of outcome-based management goals is a required component of NCCOS proposals (see FFO), and progress toward achieving management outcomes is required in NCCOS annual progress reports (see Reporting ...

Targeted Efforts to Support Nutrient Management

NCCOS supports observations and monitoring for variables that are important to modeling hypoxia in time and space. These models are then used to inform key organizations working to reduce the ...
